<< LNC2 Fixed Pitch Propeller Survey >>
The fixed pitch propeller I've been using on my LNC2 (235/320) is an
Aymar-Demuth 62 x 76. It seems to be just right - good takeoff/climb/cruise
numbers. Constant-speed would be much better, of course, but...
I did try a Sterba 64 x 78 and the overall numbers were noticeably better as
compared to the Demuth, but the ground clearance was a major consideration
and the vibration was unacceptable -- the Demuth is VERY smooth. The Demuth
prop also is a "composite" so delamination isn't a problem.
Survey info:
1) Diameter 62
2) Pitch 76
3) Manufacturer Aymar-Demuth
4) Engine horsepower 150
5) Are you satisfied with your propeller performance? YES
Cheers!
